See below for the most recent pictures of the curved steel bio-spheres in Seattle, WA. 750,000# and 1,050 pieces rectangular tube steel bent the easy way and a portion bent off-axis. Almost 8 miles of welding work and grinding was avoided because of Albina’s ability to bend a portion of the project. Almost NO correction was needed during fabrication or erection as the bends fit to the fixtures within 1/32nd of an inch﻿!

Recently a customer approached us with a very difficult steel bending project and wanted to know if Albina Co., Inc. was able to perform the difficult bends. The steel bends were for the Partnership Health Plan of California construction project. Partnership HealthPlan of California has outgrown its current home and will add a new 104,000-square-foot office building that will sit next to its current headquarters on Business Center Drive. This project consisted of primarily HSS Rectangular Tubing. The largest tube measures 20” x 8” x .375” wall and the smallest measures 8” x 4” x .500” wall. Some of the lengths were bent the easy way while other lengths were bent the hard way. Utilizing our in-house developed internal support system we roll bent all of the HSS material without any heat and exceeded all of our customers quality requirements.

Got big beams to bend? Look no further than Albina Co., Inc.! We are just finishing up a beam bending project for the Murray Amphitheater in Murray, Utah. Murray Arts in the Park provides a summer full of artistic entertainment. The evening subscription series usually opens in late May and runs through Labor Day in the Murray Park amphitheater. This project consists of 55,000# of bent wide flange the hard way. All wide flange beams were bent to a radius that is tighter than 100 ft.

Albina will not shy away from any work (within our capacity) because it might be difficult to bend. We thrive on the difficult projects that others can’t do! Stay tuned for final installation pictures.

Albina is currently working on 130,000 pounds of curved steel for the Academy Museum of Motion Pictures located in LA. Albina is bending Square Tube Steel 6″ X 6″ X .500″ WALL A500 GR B and Rectangular Tube Steel 7″ X 4″ X .500″ WALL A500 GR B (approx. 190 pcs in total to various radii and configurations). The Academy Museum of Motion Pictures will be the world’s premier film museum and a cultural institution for Los Angeles and will provide a destination for tourists to celebrate the magic and imagination of Hollywood and the movies. Check back for pictures as the project progresses.

Do you like innovative and eye catching architecture? You should take a look at the new LAX Midfield Satellite Concourse North Project. This new project is part of an estimated $1.2 billion dollar modernization program at Los Angeles International Airport. The satellite concourse will be a remote facility initially served by an airport busing operation and a passenger access tunnel (PAX) connection to the Bradley West Terminal. The new MSC will permit greater flexibility in scheduling improvements at other facilities, reduce reliance on remote gates, and ensure a high level of service for LAX passengers.

The Jan Shrem and Maria Maneeti Museum of Art at UC Davis opened in late November of 2016. Albina Co., Inc. was fortunate enough to be the designated AISC Bender/Roller on this project. Albina bent 38 lengths of tube steel 14″ X 10″ X .500″ WALL A500 GR B and 3 lengths of tube steel 14″ X 10″ X .375″ WALL A500 GR B for the complex project. All of the material bent the Easy Way, Hard Way and also compound bent the easy way AND hard way in the same length. The Fabricator on the project was Olsen & Co. Steel. SO-IL and Bohlin Cywinski Jackson designed a 50,000 square-foot permeable roof that covers both the site and the building. The canopy is composed of 910 triangular, honed aluminum infill beams. assembled in an intricate pattern, the structure seeks to evoke the patchwork texture and topology of the surrounding landscape. The canopy arcs as high as 34 feet on the freeway side, and dips as low as 12 feet at its front. The Museum is currently nominated for an AISC 2017 IDEAS2 Award.

The NCSEA (National Council of Structural Engineers Association) 19th Annual Awards for Excellence in Structural Engineering were announced in September and featured in the December issue of Structure Magazine. The facade system for the Petersen Automotive Museum Renovation was awarded Outstanding Project in the “special use structures” category. The exterior of the building was designed by Kohn Pedersen Fox as a series of freeform stainless steel ribbons flowing over the structure. The ribbons are supported by treelike structures, bent by Albina Co., Inc., which were designed to resemble engine manifolds. This project faced many structural concerns and the design team was able to come up with a solution that met all the structural needs as well as meeting the architectural vision.

Have you ever thought about what you would like your dream home to look like? Have you ever thought of using curved structural steel roof trusses on that dream home to give it that unique look and structural integrity? We just recently completed rolling 30,000# of 10″ X 2″ X .250″ WALL A500 GR B tube steel bent the hardway down to a 35 foot radius and 16″ X 4″ X .375″ WALL A500 GR B tube steel bent the hardway down to a 56 foot radius for a residence in Utah. If you are looking to design a custom home and want to learn about the benefits of using curved steel on your project, call Albina for more details.

The erection of the curved steel spheres in Seattle, Washington was completed in April 2016. Over the summer, the team of contractors began the install of the glass enclosure over the steel bio-spheres. Check out the progression in the pictures below. As a reminder, Albina’s scope of work included approximately 750,000# and 1.050 pieces of rectangular tube steel bent the easy way and a portion bent off-axis. The material was bent to tight tolerances and bent to AESS standards. The amount of welds and grinding was significant, but thanks to Albina’s ability to bend portions of the project, a significant amount of welding and grinding was avoided. Almost NO correction was needed during fabrication or erection as the bends fit to fixtures (fabrication) within 1/32nd of an inch! Check back for more pictures as the project progresses!

Some would think that a 24” tall beam weighing 84# per ft would be a big chunk of steel. One might even ask if it is possible to bend such a large section of steel. The answer would be to contact Albina. We are experts in bending the very small and the very large….you name it and we will bend it. Yes W24x84# beam is a large chunk of steel, but certainly not too large for the experts at Albina. A loyal customer out of Deer Park, Washington contacted us to bend this material the easy way down to a very tight 42 ft radius. After bending the 25,000# of steel, our customer is fabricating the sections and will eventually ship to Alaska for the new Juneau Seawalk.
